1 Claim.

This invention relates to regulator mechanisms for vehicle windows but particularly to double arm regulators for the windows of automobiles and an object is to produce a simple and efficient regulator of the above character which occupies a minimum amount of space, can be inexpensively manufactured in large scale production and is sturdy and reliable in construction and operation.

An embodiment of the invention is shown by way of illustration but not of limitation in the accompanying drawing in which Figure 1 is a side elevation of the regulator mechanism; and

Figure 2 is an edge view of. the mechanism shown in Figure 1.

The illustrated embodiment of the invention comprises a regulator mechanism for automobile windows having a, mounting plate it which is suitably secured in the door or body of the vehicle in a well known manner and mounted on the plate it are relatively large gears ii and 92 which mesh with each other. The gears H and W are secured respectively to studs it which extend through the plate ill, the opposite end of each stud being slotted to receive one end of a continuous double spiral counterbalance spring is.

The mounting plate is embossed at l5 and the spring it lies in the recessed portion thereby provided so that the outer edge thereof is substantially flush with the adjacent portion of the plate. Secured to the gear l2 and movable with the respective stud I3 is a swinging arm it which in the position shown inclines upwardly and to the right of Figure 1. It will be noted that the inner end portion llia of the arm it lies close against the outer face of the gear I2, an intermediate portion llib parallel to the portion llia is stepped outwardly therefrom and the outer end portion llic is stepped outwardly from the intermediate portion ltb but is substantially parallel with the other arm portions.

Fixed to the outer face of the gear It is a swinging arm ll which in the position shown on Figure l inclines upwardly and to the left of the figure, crossingthe arm it. As shown in Figure 1, the inner end portion of the arm i1 is substantially oval shaped providing an opening it through which the arm it extends, the connecting portion between the arm portions llib and We being disposed in the opening it and being adapted to abut against an edge thereof to limit the upward swinging movement of the arms. The arm H has a portion l'la which abuts flatly against the outer side of the gear l l and to which it is rigidly secured and intermediate portions llb in the form of opposed side portions which are parallel to the portion lid and an outer portion ilc which is stepped outwardly but is disposed in parallel relation to the other arm portions.

On the outer ends of the arms it and ll are buttons or studs it having outer conical portions with which a spring tensioned washer 2t cooperates. The studs l9 engage in the usual longitudinally elongate guide or slot of the retainer fixed to the lower edge of the window glass so that swinging movement of the arms it and ii in one direction moves the window glass in one direction and swinging movement of the arms in the opposite direction moves the window glass in an opposite direction, as will be readily understood. Upon downward swinging movement of the arms it and ll, it will be apparent that the spring M is placed under a tension to assist in the movement of the arms in the opposite or upward movement.

An important feature of this construction resides in the mounting of the cross arms on the same side of the mounting plate thereby afford-- ing a more comp-act construction and greatly simplifying the construction and arrangement of the parts. Heretofore, it has been necessary in a cross arm regulator to have one arm on one side of the mounting plate and the other arm on the opposite side. This involves a costly and unsatisfactory arrangement. Furthermore, the present construction enables the use of a double spring which was not possible in the previous regulators of this type.

For manually driving the gears ii and i2, a. relatively small gear it meshes with the gear H. The gear 2! is carried by a larger gear 22 with which a pinion 23 forming a part of a spring clutch 2t meshes. The spring clutch is, wellknown to those skilled in this art and detailed description thereof is not considered necessary. Sufiice it to say that the clutch or brake enables the parts to be driven in one direction but prevents retrograde movement thereof. A squared shaft 25 also forming a part of the clutch is adapted to receive the usual crank handle (not shown) for manually operating the regulator.

It is to be understood that numerous changes in details of construction, arrangement and operation may be effected without departing from the spirit of the invention especially as defined in the appended claim.

What I claim is:

Window regulator mechanism comprising a mounting plate, a pair of meshing gears on said plate, means for operating said gears, a pair of cross arms fixed at their inner ends to said gears respectively, the outer end portions of said arms being disposed in a plane parallel to the inner end portions thereof and in substantially the same plane relative to each other, one arm being apertured and the other arm extending freely through such aperture for free swinging movement within a limited arc, the free ends of said arms being adapted to be operatively connected to a Window.
